OPTIONS

15       -h, --help
16              display this help and exit
17

25              set member size limit in bytes
26
27       -c, --stdout

44
45       -m, --match-length=<bytes>
46              set match length limit in bytes [36]
47
48       -o, --output=<file>
49              if reading standard input, write to <file>
50
51       -q, --quiet
52              suppress all messages
53
54       -s, --dictionary-size=<bytes>
55              set dictionary size limit in bytes [8 MiB]
56
57       -S, --volume-size=<bytes>
58              set volume size limit in bytes, implies -k
59
60       -t, --test
61              test compressed file integrity
62
63       -v, --verbose
64              be verbose (a 2nd -v gives more)
65
66       -0 .. -9
67              set compression level [default 6]
68
69       --fast alias for -0
70
71       --best alias for -9
72
73       --loose-trailing
74              allow trailing data seeming corrupt header
75
76       If  no  file  names  are given, or if a file is '-', lzip compresses or
77       decompresses from standard input to standard output.   Numbers  may  be
78       followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 = 1024,
79       M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...  Dictionary  sizes  12
80       to 29 are interpreted as powers of two, meaning 2^12 to 2^29 bytes.
81
82       The  bidimensional  parameter space of LZMA can't be mapped to a linear
83       scale optimal for all files. If your files are large, very  repetitive,
84       etc,  you  may  need  to  use  the --dictionary-size and --match-length
85       options directly to achieve optimal performance.
86
87       Exit status: 0 for a normal exit, 1 for  environmental  problems  (file
88       not  found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
89       invalid input file, 3 for an internal consistency error (eg, bug) which
90       caused lzip to panic.
